The 8-letter word “SNATEREN” is an obsolete verb meaning “to quack” or “to make a harsh, high-pitched sound.” It is thought to be derived from the Dutch word “snaateren,” which has the same meaning. The word is no longer in common use, but it can still be found in some older dictionaries and literature.
Here is a sentence using the word “snateren”:
